Name a chemical change in the digestive system.
Enzymes break down food; stomach acid breaks down food even more. Saliva breaks down food particle.
200
What is adaptation?
a change or the process of change by which an organism or species becomes better suited to its environment
200
This organelle regulates what enters and leaves the cell and provides protection and support
Cell membrane

When you eat a slice of pizza, what energy transformation takes place from the pizza that is already in the digestive system to the rest of your body to keep you warm?
Chemical energy to thermal energy.

What are the steps of energy transformation in photosynthesis?
Radiant or light energy from the sun changes to chemical energy.
400
Is adaptation a want or a need?
A need.
400
This organelle is usually larger in plant cells and is a storage place for nutrients within the cell
Vacuole
500
What major macromolecule is found in ice cream?
Carbohydrates

How do the circulatory and respiratory system work together?
Respiratory system brings in the oxygen, and the circulatory system carries the oxygen to the rest of the body. Circulatory system brings the carbon dioxide waste to the lungs, and the respiratory system breathes the carbon dioxide out as waste.
500
Once food is converted to chemical energy, what 2 energy forms come from the chemical energy?
Mechanical (OR kinetic energy) and thermal energy
500
Why are the spikes on a porcupine considered a structural adaptation?
Because it is a part of the porcupine that can be seen and helps the porcupine adapt to its environment by fending off predators.
